Barr saved her most heated exchange for her former TV son Michael Fishman, 36, accusing him of throwing her "under the bus."

After learning the series was canceled on Tuesday, a "devastated" Fishman shared an emotional message with fans.

"Today is one of the hardest in my life," Fishman tweeted. The actor went on to "condemn" Barr's remark, and pointed out that in the "Roseanne" revival his character, D.J. Conner — who was in an interracial marriage and had a black daughter — "was designed to represent the inclusive nature of my views. To represent portions of society often marginalized."

Wednesday morning, Barr angrily responded to Fishman's message.

"I created the platform for that inclusivity and you know it. ME. You throw me under the bus. Nice!" she tweeted.

"You fought, built, and designed 'Roseanne' for inclusiveness. That is why yesterday was so out of character with the last 30 years. It was in your hands from the beginning to the end. No one can deny that," he wrote.

Syndicated reruns of the original "Roseanne" series were also dropped from multiple channels as a result of Barr's tweet, and her talent agency, ICM Partners, announced they'd dropped the star as a client.
